About this 3D model

Just a small Filament guide for my Prusa I3. It will prevent that the Filament jumps out of your spool, or at least help. Printed with PETG for the flexability, but other materials are ok too. I heated up the part and bent it like seen in the picture for more Z height. Dont print the full Z height with this mod as the extruder might crash against it, also dont expand x/y too much at high Z levels as the filament would bend too much after it passes thrue the ring. No support needed, dont forget to remove the small overhang support i added at the top.
